胶质细胞

All 7 cases were characterized by deposition of dystrophic or psammatous calcifications accompanied with chronic inflammatory cells infiltration in the stroma. In some cases, there was formation of germinal centers.

特徵性形态学表现为在胶原化的纤维组织间可见散在的钙化灶或砂砾小体，间质内伴有多少不等的淋巴细胞和浆细胞浸润灶，部分病例中可见生发中心形成。

The top quality antioxidants skin care products have an additional function; they stimulate the cells to make collagen and elastin.

最高质量的抗氧化剂皮肤护理产品有更多的功能；他们刺激细胞，使胶原质和弹性蛋白。

OBJECTIVE: To investigate the effect of propolis flavone on expression of MMP-9 in human umbilical vein endothelial cell.

目的：拟证实蜂胶黄酮对人脐静脉内皮细胞基质金属蛋白酶9表达的影响。

The collagen subtypes Ⅰ and Ⅲ are essential components of the cardiac extracellular matrix maintaining the functional integrity of the heart.

型胶原是心肌细胞外基质的基本组成成份，对保持心功能的完整性起着重要作用。

Attachment of chondroitin sulfate appeared to promote cellular ingrowth and cartilaginous tissue formation in both types of collagen matrices.

在两种胶原基质粘附硫酸软骨素，促进细胞的长入和软骨组织的形成。

They synthesize and secrete an organic extracellular matrix, osteoid, which is composed primarily of type I collagen.

它们分泌、合成细胞外基质和主要含有I型胶原的的类骨质。

In order to overcome the shortcomings of acellular dermal matrix used as tissue engineering scaffold material, such as bad permeability, low degradation speed, and strong immunogenicity, a new type of collagen scaffold was prepared by applying various chemical, biological and physical comprehensive methods to deal with pigskin. The microstructure of the scaffold was observed under photomicroscope and scanning electron microscopy, and the in vitro degradation time, permeability, tensile-strength, porosity, shrinkage temperature were tested.

为了克服猪脱细胞真皮基质作为组织工程支架材料渗透性差、降解速度过慢、免疫原性较强等缺点，采用多种化学、生物与物理综合方法处理猪皮制备了一种新型天然胶原支架材料，通过光学显微镜、扫描电镜观察以及体外降解时间、透水汽性、拉伸强度、孔隙率、收缩温度等的测定，对其性能进行了研究。

Results］the gross morphology of the tendons showed the experimental group had lesser adhesion and better reactiveness than that in the control group.the fibrin had degraded at 3 weeks. cell tracing showed that the labeled bone marrow derived mesenchymal stem cells remained viable and presented in the intratendinous region for at least 6 weeks, becoming more diffuse at later timepoints.at 3 weeks, collagen fibers appeared more organized and there were better morphometric nuclear parameters in the treatment group. at 6 and 12 weeks, there were no differences between the groups with regard to morphometric nuclear parameters.

结果］实验组相比对照组肌腱大体观察粘连差，肌腱活动性好。3周后纤维蛋白载体即降解，细胞示踪结果显示标记的骨髓间充质干细胞至少6周内仍可保持活性并存在于肌腱组织中，但之后逐渐扩散。3周时，实验组与对照组相比胶原纤维排列更为有序，且胞核形态结构更规则，但在6周及12周时，实验组与对照组胞核参数测定无统计学意义。3周时实验组比对照组具有更强的的生物力学特性，但之后则差别不明显。

3Chondrogenesis was assessed using Alcian blue staining, Toluidine bluestaining, Safranin O/Fast Green staining at 7 and 14 days, still collagenⅡimmunohistochemistry and aggrecan immunofluorescence at 4, 7 and14 days after initial chondrogenic induction of adipose -derivedmesenchymal stem cells.

3观察脂肪间充质干细胞在诱导后的生长增殖情况、形态变化，于诱导7、14天后应用阿尔新兰染色、甲苯胺兰染色、藩红0／固绿染色，以及4、7、14天后应用Ⅱ型胶原蛋白免疫细胞化学、aggrecan免疫荧光评价其成软骨能力。

The extracellular matrix wasstained positively for Alcian blue, Toluidine blue and Safranin O / FastGreen at 7 and 14 days after initial chondrogenic induction of adipose -derived mesenchymal stem cells, and indicated collagenⅡand aggrecanwere expressed positively.

2脂肪间充质干细胞在高密度的"微团"培养条件下，于诱导7、14天后阿尔新兰染色、甲苯胺兰染色、藩红0／固绿染色阳性，诱导4、7、14天后Ⅱ型胶原蛋白免疫细胞化学、aggrecan免疫荧光阳性表达。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。

Go down on one's knees;kneel down

屈膝跪下。。。下跪祈祷
